Vibrations from instantaneous and millisecond CORE

Vibrations from instantaneous and millisecond-delayed quarry blasts / By James F. Devine, Alfred V. C. Meyer, Charles F. Johnson and Wilbur I. Duvall. Abstract.

Influence of millisecond time, charge length and

The law of blasting vibration caused by blasting in rock is very complex. Traditional numerical methods cannot well characterize all the influencing factors in the blasting process. The effects of millisecond time, charge length and detonation velocity on the blasting vibration are discussed by ...
